Abstract: An apparatus for processing data has a plurality of single-bit processing elements coupled together to form an m×n processing element array, where m is an integer number of rows and n is an integer number of columns. Each processing element has addressable storage for storing pixel data in an array format in which each addressable storage holds all of the bits associated with one pixel; and the processing element array includes a mechanism for providing direct read/write access to the addressable storage located in any addressed row of the processing element array without requiring that data be passed through other rows of the array.
